To all whom, it Trmy concern.-

Be it known that 1, JOHN J. BUCHANAN, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Buckles; andI do hereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent in Figure1 a view in front elevation of my improved buckle. Fig. 2 an edge viewthereof. Fig. 3 a .rear view thereof. Fig. 4 a view thereof in verticalsection and shown as webbed. Fig. 5 a detached view in rear elevation ofthe sheet-metal clamping-plate of the buckle-frame; Fig. 6 a detachedperspective view thereof looking at its lower edge. Fig. 7 a viewthereof in vertical section on the line a b of Fig. 5. Fig. 8 a view ofthe buckle in vertical section with the lever lifted into its openposition, this view being particularly intended to show the threadingspace between the lower edge of the clamping-plate and the lower bar orside of the wire body of the frame.

My invention relates to an improvement in that class of lever-buckles inwhich the buckle-frame consists of a wire body and a sheet-metalclamping-plate, the object being to reduce the frame of such a buckle tothe minimum width and at the same time to facilitate the application ofthe webbing to it.

W ith these ends in view my invention con- 'sists in a buckle havingcertain details of construction as will be hereinafter described andpointed out in the claim.

In carrying out my invention as herein shown, the buckle-frame consistsof a sheetmetal clamping-plate 2 having an upwardly proiecting yieldingtongue 3 and formed at its ends with extensions bent to form verticalsockets 4 which clasp the straight lower por tions 5 of the ends of thewire body which is made from a single piece of wire bent to form ahorizontal lower bar or side 6, ends compristhe said straight lowerportions 5 and foring wardly inclined upper portions 7, and pintles 8which are parallel with the lower bar 6 and form, in effect, the upperside of the buckleframe. The said pintles 8, are embraced by the sockets9 of a buckle-lever made of a single piece of sheet-metal and consistingof a finger-piece l0 and a clamping edge 11 which latter presses therunning portion 12 of the webbing against the outer face of the tongue 3of the plate 2. For the purpose of bringing the edge 11 into rightposition with respect to the plate 2 the upper portions 7 of the ends ofthe wirc-body are as above described set forward at an angle as shown inFigs. 4 and 8.

It will be noticed that the depth of the buckle-frame, so to speak, orin other words, the distance between its upper and lower sides or thedistance between the pintles 9 forming its upper side and the lower bar6 forming its lower side is narrow compared with ordinary buckles of theclass to which this buckle belongs. In order, therefore, to secure thespace required for webbing the buckle, I set the lower edge or portionof the plate 2 between the sockets 4, forward at an obtuse angle so asto form a threading space or webbing opening 1. 3 as best shown in Fig.

8. Incidentally the portion so struck forward forms a beveledguide-surface 14 which, when the end 15 of the webbing is inserted fromfront to roar, deflects the said end downward and makes the task ofwebbing easy. By carrying the lower edge or portion of the plate 2forward as described, I am enabled to make the buckle frame relativelynarrow; otherwise the wire-body of the frame would have to be made deepenough to carry the lower bar or side 6 thereof sullicicntly below thelower edge of the plate 2 to give the space required for the freepassage from rear to front of the webbing. The reduction of thebuckle-frame in width as described, not only reduces the amount of metalused and thus effects an economy, but also makes the buckle smaller andneatcr.

I would have it understood that I do not limit myself to the exactconstruction herein shown and described but hold myself at liberty tomake such changes therein as fairly fall within the spirit and scope ofmy claim. I00

I claim In a lever-buckle, the combination with a buckle-framecomprising a wire-body having a lower side, and a sheet1netalclampingplate the lower portion of which is set forward at an obtuseangle; of a buckle-lever pivoted upon the said wir in position to oo-actwith thereof, the setting the clamping-plate forward of the lower edgeof the said plate forming a threading space 5 between its lower edge andthe lower side of the said wire-body whereby the frame may be reduced inwidth and also whereby the threading of the webbing is facilitated.

e-body of the frame In testimony whereof, I have signed this specifcation in the presence of two subscribmg witnesses.
